Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1039644, here are decompositions:

13 + 1039631 = 1039644
37 + 1039607 = 1039644
41 + 1039603 = 1039644
101 + 1039543 = 1039644
107 + 1039537 = 1039644
127 + 1039517 = 1039644
131 + 1039513 = 1039644
163 + 1039481 = 1039644

Showing the first eight; more decompositions exist.
